Tella

YES

Replaceable in one session with an AI coding agent.

Screen and camera recording in the browser, edited as a sequence of clips rather than a timeline, with backgrounds and layouts for demo videos.

Promptfree, for everyone, and the only version there is

Build browser recording with clip-based editing.

STACK
- getDisplayMedia and getUserMedia, MediaRecorder, ffmpeg.wasm or a server worker

RECORDING
- Two streams: screen and camera, recorded separately rather than composited live
- Separate tracks mean the layout can change after the fact, which is the whole idea
- Write chunks to IndexedDB as they arrive; never hold a long recording in memory

CLIPS
- A clip is a start and an end within a take, plus a layout choice
- Deleting a clip never touches the source; the edit is a list of ranges

RENDERING
- Compose on a canvas frame by frame, or send the ranges to a server worker running ffmpeg
- Server rendering is more reliable for anything over a few minutes

Include the recorder, the clip model and the render pipeline.

What you lose

Recording screen and camera together in a browser, with the layouts already designed
Clip-based editing that avoids a timeline entirely, which is why non-editors can use it
Hosting and sharing of the finished video

If you would rather not build

Loom, for the hosted version
ffmpeg with a shell script
